Description

FIELD OF THE INVENTION

[0001] The present invention relates to a locking hub system for a vehicle, and more particularly to a vacuum actuated locking hub cartridge with reduced assembly length and improved assembly, installation and sealing capabilities.BACKGROUND AND SUMMARY OF THE INVENTION

[0002] Vehicles having four-wheel drive capabilities that are designed for on-road and off-road use typically provide optional engagement / disengagement of two of the four wheels. The wheels to be disengaged are necessarily provided with a driveline from the vehicle powertrain wherein for on-road use and to avoid unnecessary energy consumption and wearing of the out-of-service driveline components, hub locks are provided for disconnecting the axles from the wheels of the vehicle. The original hub lock devices were manually actuated. A driver / operator would stop the vehicle, engage the transfer case disconnect system and then manually turn a dial located in each wheel hub to activate the hub lock to ...
